Health & Welfare
A study aimed to determine safe levels of ammonia and nitrite to various life stages of the Amazon river prawn, based on the hypothesis that the early stages of development of M. amazonicum are more sensitive to ammonia and nitrite than later stages. The monitoring of this variable is important to avoid losses, mainly in larviculture and recirculation.
Health & Welfare
In a 60-day study, Amazon River prawn postlarvae stocked in pens within a culture pond were given commercial feed or received no feed beyond the natural organisms in the pond.
Aquafeeds
Low-input culture practices for freshwater prawns can manage their growth and biological characteristics so they can be fed no fishmeal or fish oil.
Responsibility
A practical way to treat mariculture effluents combines the physical attributes of a sand filter and the biological properties of hungry marine sand worms.
Responsibility
The inadequate supply of postlarvae is a bottleneck for prawn production in Bangladesh. A shortage of wild broodstock to supply the hatcheries is an ongoing concern.
Responsibility
Prawn-fish-rice farming is considered highly efficient in terms of resource utilization through the complementary use of land and water. Integrated prawn farming plays an important role in the economy of Bangladesh, earning foreign exchange, increasing food production and providing employment opportunities.
